The diificulty commonly experienced. in

The only sat-v purpose is the stationary opener 'which vis secured as a more or'less permanentjfixture in all'restaurants, cafs,-bars, etc., and pos-' sesses the requisite strength, rigidity and leverage to permit of aquick removal of the cap. I V difiiculty experienced in the removal'ofthe closure is due in great part to thefa ct that the greater the stress upon the sealing flange at a single point, the tighter it binds around the sides of the bottle neck since the tendency is for the flangeto take on an oval form of less width in its shortdiameter than that of the original circular cap, thus pressing its indentations the more firmly beneath It frequently happens cap tears across before the flange spreads at the sides enoughfor its indentations to clear the annular depression in the bottle neck into which they are forced.

We have fou1d that the cap may be readthe annular rim. that the metal of the V ily removed by hand by means 0 a tongue A of convenient length and'relatively broad' base B, integral with the cap. To give this tongue the requisite strength we propose to State of New York, g V
